Title: Improvements in the manufacture of metal articles
IPC: B22F3/00
Filed: 1953-12-04
Abstract: A method of forming a metal article of finite shape and less than solid density form an oxygen-bearing compound of the metal comprises reducing a loose mass of particles of the compound at less than melting temperature, supporting the metal particles in a shaping structure and heating to cause coherence of the particles to form an article conforming to the shape of the structure and removing the article from the structure.  The oxygen-bearing compound of fine particle size and predetermined size distribution may be placed in the shaping structure prior to reduction.  The article e.g. a slab, may be worked under such conditions that the differential deformation is not greater than about 5 per cent in one rolling step, or the article may be worked to maximum density in a single step.

Abstract: 867,860. Making foil; cold-rolling. IMPERIAL CHEMICAL INDUSTRIES Ltd. Jan. 30, 1959 [Oct. 30, 1957], No. 33838/57. Drawings to Specification. Classes 83 (2) and 83 (4). In a method of rolling a strip or sheet of a first metal or alloy having a Vickers Diamond Pyramid Hardness (V.P.N.) not greater than 400, said strip or sheet is cold-rolled together with a strip or sheet of a softer metal or alloy, the ratio of the V.P.N. before rolling of the first metal or alloy to that of the softer metal or alloy.being from 1.1/1.0 to 5.0/1.0, the amount of reduction being such that the superimposed strip or sheet remains separate after rolling. Frictional forces set up at the rolled interface are said to increase the degree of reduction attainable, e.g. to 0.0088 inch thick, in a given mill and also to result in load economy for a given reduction. Titanium may be reduced while sandwiched between two strips or sheets of 70/30 or 63/37 brass or between high conductivity copper or alternatively while rolled with a single sheet of brass. Brass (70/30) may likewise be reduced using commercially-pure aluminium as the soft metal. The strips or sheets are annealed prior to rolling. A single sheet of the softer metal may be folded about a sheet of the harder metal or a number of sheets or strips of hard and soft metal or alloy may be interleaved and rolled. Two strips or sheets of the harder metal may be sandwiched between a pair of strips or sheets of the softer metal.

Title: Drag shoe devices for vehicles
IPC: B60T1/14
Filed: 1932-12-07
Abstract: 411,175. Skid brakes. BORJYMSKY, T. M. VON, 32, Rue de Boulainvilliers, Paris. Dec. 7, 1932, No. 34661. [Class 103 (i).] A brake shoe which is adapted to be lowered into engagement between a vehicle wheel and the track is raised by driving mechanism which is automatically put out of action when the shoe reaches a predetermined ineffective position. The driving gear may be driven by hand, electric motor, or by the wheel axle or a shaft geared thereto. In Fig. 3, the brake shoe 1 mounted upon arms 2 pivoted upon the axle of the wheel 3 is raised by a cable 6 wound upon a drum 7 driven by a handle 34 through a clutch 33 and chain 30. When the shoe reaches a predetermined raised position, a projection 27 on the drum strikes a rod 24 which through a bell-crank 35 disengages the clutch. The shoe may be retained in the raised position by a detent which can be released by the driver to allow the shoe to fall. The shaft 37 may be driven from a power source instead of by hand, for example from the gear box of a motor vehicle. In another arrangement the drum 7 is geared to an electric motor in the circuit of which is a switch comprising a sliding element which is pushed to break the circuit by a projection and rod such as 27, 24. In Figs. 5, 7, 7<a>, the shoe is raised by reverse movement of the vehicle. The shoe is retained in the raised position by a spring catch 61, 60 of which the element 60 is pivoted on a fixed bracket 53 and carries the armature of a magnet 56. The arm 2 which carries the shoe 1 and which pivots about the axle 40 is secured to one member 39 of a ball ratchet clutch, the other member 43 of which is slidably keyed upon the axle. The balls 42 are normally out of alignment with the projections 41 so that the clutch is inoperative in either direction of rotation of the axle. By momentarily energizing the magnet 56 the shoe 1 drops into operative position and the movement of the catch member 60 towards the bracket 53 after disengagement of the shoe actuates, through connections 50, the fork 46 to move the balls into the effective position shown in Fig. 7<a>. Upon reversing the vehicle the rotation of the axle then raises the shoe until the outward movement of the catch member 60 as it receives the member 61 returns the clutch to the inoperative position. Specification 411,176 is referred to. Reference has been directed by the Comptroller to Specifications 15435/90, 13863/91, and 15362/92, [all in Class 108].
